For the fourth quarter of 2012, sales increased 4.5% to $71.8 million
compared to $68.6 million for the fourth quarter of 2011. For 2012,
sales decreased 2.9% to $286.6 million compared to $295.1 million for
2011.

For the fourth quarter of 2012, the GAAP net loss was $2.5 million, or
$0.21 per Class A share and $0.22 per Class B share, compared to GAAP
net earnings of $82,000, or $0.00 per Class A share and $0.01 per
Class B share, for the fourth quarter of 2011. For 2012, GAAP net
earnings were $2.4 million, or $0.17 per diluted Class A share and
$0.21 per diluted Class B share, compared with GAAP net earnings of
$3.8 million, or $0.28 per diluted Class A share and $0.33 per diluted
Class B share, for 2011

Restructuring charges of $3.1 million for the fourth quarter of 2012
and $5.2 million for 2012 are expected to result in annual operating
cost reductions of about $5.6 million beginning in 2013.

For the fourth quarter of 2012, non-GAAP net earnings which excludes
restructuring charges, acquisition costs and other charges increased
to $979,000, compared to non-GAAP net earnings which excludes
restructuring charges, litigation charges and other charges for the
fourth quarter of 2011 of $395,000. For 2012, non-GAAP net earnings
rose to $7,365,000 compared to $7,085,000 for 2011.

Bel agreed to acquire the Transpower magnetics business of TE
Connectivity, which had 2012 sales of about $75 million. Expected to
close in the first quarter of 2013, this acquisition will solidify
Bel's position as a world leader in integrated connector modules
(ICMs).

Purchased 279,000 Class B common shares (for an aggregate cost of $4.9
million) in the fourth quarter of 2012 and 369,000 Class B common
shares (for an aggregate cost of $6.6 million) for all of 2012 under
the $10 million common share buyback program authorized by the Board
in July 2012.

CEO comments

Daniel Bernstein, Bel's President and CEO, said, "In 2012, we made
substantial progress implementing our strategy to improve Bel's short
and long-term growth in revenue and profitability.

"Our first step was to immediately improve Bel's competitiveness and
profitability in our existing products. The restructuring program we
completed in 2012 was designed to reduce operating expenses by about
$5.6 million annually, beginning in 2013. Our GAAP net loss for the
fourth quarter of 2012 primarily reflects the costs of this
restructuring. On a non-GAAP basis, excluding costs detailed in the
table reconciling GAAP to non-GAAP financial measures included in this
release, net earnings for the fourth quarter of 2012 more than doubled
versus the same quarter last year.

"We also agreed to acquire, for approximately $22.4 million in cash, the
Transpower magnetics business of TE Connectivity, which had 2012 sales
of approximately $75 million and is expected to be accretive to Bel's
earnings following the anticipated closing of the transaction by the end
of the first quarter of 2013. Included in this acquisition are ICM
products, including RJ45, 10/100 Gigabit, 10G, PoE/PoE+, MRJ21, RJ.5, a
line of modules for smart-grid applications and discrete magnetics. We
expect this expanded product line will double our sales of ICMs and
related components, enabling us to further improve Bel's cost structure
and enhance our competitive position in the market for ICM-related
components. At closing, Bel will also receive a license to produce ICM
products using TE's planar embedded magnetics technology.

"Our next step was to add product lines which have the potential for
significant growth over the next two to three years. A key component of
this plan was our recent acquisition of Milan-based Powerbox, which is
intended to add established AC-DC products to our existing power
portfolio. In addition to established products, the Powerbox acquisition
provides Bel with valuable design and manufacturing capabilities which
will supplement our skill sets in Europe, China and the United States.
We believe that over the next few years, the AC-DC power transformer
business can grow, through our current customer base, to over $30
million of annual revenue.

"The third stage of our growth plan includes development of fiber optic
products which we believe will become an industry standard for aerospace
military markets over a three to five-year horizon. Two small but
important acquisitions completed in 2012 set the foundation for this
initiative, and also contributed to sales growth in the fourth quarter
of 2012. U.K.-based Fibreco and Gigacom Interconnect AB have now been
integrated into Bel's Cinch Connectors business. We believe the
combination of Fibreco's broad range of expanded beam fiber-based
connectors and Gigacom's expanded beam EBOSATM products will
enable Cinch to be a leader in fiber connector technology. Because of
the quality, reliability and weight benefits of fiber products in
comparison to copper components currently being used in the aerospace
and military markets, we see significant growth opportunities in this
area. The mil/aerospace market can represent as much as a third of Bel's
total sales within five years.

"Taken together, these actions have set a clear strategy for the Company
over the next five years."

Fourth Quarter Results

For the three months ended December 31, 2012, net sales increased to
$71,752,000 compared to $68,642,000 for the fourth quarter of 2011,
reflecting the contributions of the acquired businesses as well as
higher sales of magnetics and circuit products, partially offset by
lower modular product sales. Cost of sales decreased to 84.3% of sales
for the fourth quarter of 2012, compared to 85.1% of sales for the
fourth quarter of 2011.

The operating loss for the fourth quarter of 2012 was $3,117,000,
compared to operating income for the fourth quarter of 2011 of
$1,084,000. Excluding costs detailed in the table reconciling GAAP to
non-GAAP financial measures included in this release, non-GAAP operating
income was $928,000 for the fourth quarter of 2012, compared to
$1,301,000 for the fourth quarter of 2011.

The net loss for the fourth quarter of 2012 included an income tax
benefit of $688,000, the result of pre-tax losses during the quarter.
For the fourth quarter of 2011, income tax expense was $1,078,000.

The net loss for the fourth quarter of 2012 was $2,537,000, compared to
net earnings for the fourth quarter of 2011 of $82,000.

Excluding the charges detailed in the table reconciling GAAP to non-GAAP
financial measures mentioned above, non-GAAP net earnings for the fourth
quarter of 2012 were $979,000. This compares to non-GAAP net earnings
for the fourth quarter of 2011, excluding charges detailed in the
reconciliation table, of $395,000.

The net loss per Class A common share for the fourth quarter of 2012 was
$0.21, compared to net earnings per diluted Class A common share of
$0.00 for the fourth quarter of 2011. Adjusted to exclude the amounts
referenced above, non-GAAP net earnings per diluted Class A common share
were $0.08 for the fourth quarter of 2012, compared to $0.10 for the
fourth quarter of 2011.

The net loss per Class B common share was $0.22 for the fourth quarter
of 2012, compared to net earnings per diluted Class B common share of
$0.01 for the fourth quarter of 2011. Adjusted to exclude the amounts
referenced above, non-GAAP net earnings per diluted Class B common share
were $0.09 for the fourth quarter of 2012, compared to $0.11 for the
fourth quarter of 2011.

The non-GAAP measures presented above are not measures of
performance under accounting principles generally accepted in the
United States of America ("GAAP"). These measures should not be
considered a substitute for, and the reader should also consider,
(loss) income from operations, net (loss) earnings, (loss) earnings
per share and other measures of performance as defined by GAAP as
indicators of our performance or profitability. Our non-GAAP
measures may not be comparable to other similarly-titled captions of
other companies due to differences in the method of calculation.

Based upon discussions with investors and analysts, we believe that
the reader's understanding of Bel's performance and profitability is
enhanced by reference to these non-GAAP measures. Removal of amounts
such as charges for restructuring, severance, reorganization, losses
on the disposal of property, plant and equipment, costs related to
Hurricane Sandy and acquisition-related costs facilitates comparison
of our results among reporting periods. We believe that such amounts
are not reflective of the relevant business in the period in which
the charge is recorded for accounting purposes.

(2)

Net of income tax at effective rate in the applicable tax
jurisdiction.

(3)

Individual amounts of net (loss) earnings per share may not agree to
the total due to rounding.
